Can Fran pull her game together before it's too late?

Fran Cullers is having a horrible summer. She was a star player on the Little League team in her old town, so the Highwater Hardwares should be thrilled to have her-except that they hate girls. She can run rings around these guys, but they won't even give her a chance. So Fran sets out to destroy the Hardwares.
